CURTAIN FOR LAMP SHADES 0R DOMES.

Patented Dec. 6. 1921.

Application filed April 28, 1921. Serial No. 465,085.

To all whomit may concern:

Beit .known that I, HENRY AUGUST F.

KUnnn, a citizen of the United States, and a resident of the city of NewYorkyborough of Brooklyn, in the county of Kings and State of New York,have invented a new and Improved Curtain for Lamp Shades or Domes, ofwhich the following is a full, clear, and exact description.

The invention relates to lighting fixtures, and its object. is toprovide a new and mm proved curtain more especially designed for use onlamp shades or domes and arranged to permit the user of the lamp toreadily shade the eyes against the direct rays of light. emanating fromthe burning lamp.

Another object is to provide a curtain which is normally in inactive,"out ofsight position, and can be readily drawn into actlve position bythe user of the lamp.

Another object is to permit of conveniently and quickly attaching thecurtain to the lamp shade or dome.

lVith these and other objects in view, the invention consists of certainnovel features of construction, as hereinafter shown and described andthen specifically pointed out in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings forming. a part of this specification, in whichsimilar characters of reference indicate corresponding parts in all theviews.

Figure l is a plan view of the improved curtain as applied to a dome,the latter being shown in section;

Fig. 2 is an enlarged sectional side elevation of the same on the line2-2 of Fig. 1;

Fig. 3 is an enlarged sectional side elevation of the spring end of thecurtain roller;

Fig. l is an end elevation of the improved curtain with the supportingframe shown in section; and

Fig. 5 is a perspective view of a modified form of curtain as. appliedto the dome shown in section To the inner face of the lower portion of alamp shade or dome 10 is secured a frame 11, preferably made of springwire bent into hexagonal or other polygonal shape with the corners 12rounded off and bearing against the inner face of the dome by theresiliency of the spring frame. On any one or on two or more of thesides 13 of the frame 11 are hooked brackets 15, 16 provided at theirlower ends with bearings 17 and 18 in which are journaled the ends of aspring controlled roller 20 on which winds a curtain 21 of silk or othersuitable flexible material. The roller 20 at the bearing 18 of thebracket 16 is made hollow to receive a spring 25 fastened at one end tothe roller and at the other end to the bearing 18, and this spring iswound up on pulling the curtain 21 downward and thereby rotating theroller 20. When the curtain 21 is drawn downward into open position, asshown in Fig. 2,then

it extends below the dome 10 and thus shades the eyes of the user of thelamp against the direct rays of the light emanating from the lamp ofwhich the dome 10 forms a part.

In order to hold the curtain 21 in extended position use is made of twospring pawls 26 and 27 forming part of the bearing 18 and adapted toengage grooves 28, 29 formed lengthwise 011 the hollow end of the roller20, as plainly shown in Fig. 3. It is understood that when the curtain21 is drawn down and the roller 20 is thereby rotated then the spring 25is placed under compression and the roller is locked against aocidentalreturn movement by the pawls 26, 27 engaging the shallow grooves 28 and29. When it is desired to return the curtain '21 to inactive, wound-upposition then a slight pull on the curtain turns the roller 20sufficiently to disengage the pawls 26, 27 from the shallow grooves 28.29, and then on the operator quickly releasing the curtain 21 the spring25 turns the roller 20 with a view to wind up the curtain 21.

It will be noticed that the frame 11 can be readily sprung into positionon the inner face of the lower portion of the dome or lamp shade l0, anda pair of brackets 15, 16 with a roller 20 journaled thereon can bereadily hooked onto any one of the sides 13 of this frame to locate thecurtain 21 in the proper position to shade the eyes of the user of thelamp. It will also be noticed that when the curtain 21 is in wound-upposition it is completely concealed within the dome 10 together with thesupporting frame 11 and hence the attachment does not affecttheappearance of the dome 10.

Instead of using the supporting frame 11, use may be made of shaderoller brackets 40 mounted or otherwise attached to the inner face ofthe lower portion of the dome 10, as indicated in Fig. 5. It isunderstood that the brackets 40 support the roller 11 on which winds thecurtain 4E2.

Having thus described my invention, I claim as new and desire to secureby Letters Patent;

1. A curtain for lamp shades 0r domes, comprising a frame made of apieceof spring wire bent into polygonal shape, the corners of the framefrietionally engaging comprising a frame made of a piece of spring wirebent into polygonal shape, the corners of the frame frictionallyengaging the inner face of a lamp shade or dome. brackets suspended fromthe sides off the said frame and arranged in pairs, a springcontrolledshade roller jonrnaled in the said pairs of brackets and having anexterior groove at one end. a spring pawl adapted to engage the saidgroove and mounted on the adjacent bracket, and a curtain o'l flexiblematerial Winding on the said roller.
